To all whom t 'may concern: f

Be it known that I, JOHNH. SHAW, a citizen of the United States,residing in the city and county of New VHaven, Statenf- Connecticut,have invented certain new and useful Improvements in Locks, of whichthefollowing is a full, clear, und exact descrip'- tion. v i' Thisinvention relates to locks, andy more particularly to rimlocks'providedwith a roller bolt and with means for operating this typeof bolt. v' The vprimary object of my invention is to n provide novelmeans for rotating the type of bolt herein disclosed into and out of itslocking position. n l

` Another object of myl invention is to improve the construction andoperation of the type of `bolt which is designed tobe rocked upon-a pairof tru'nnions into and outl of locking engagement with a projectingstaple.

Still another object of my invention is vto improve the construction,operation and arrangement of parts in the type of lock to which thisinvention relates.

To these and other ends the inventionconsists in the novel features andcombinations of parts to be hereinafter described and claimed.

In the accompanying drawings:

Fig. 1 is a central sectionalview takenk longitudinally throu `h a lockembodying 4my invention as applic to a door, a portion of the door anddoor frame being y,shown in section.

Fig. 2 is an inside view of the lock shown in Fig. 1, the cap platebeing removed to disclose the interior of the lock, the mecha# nismbeing shown in its lockedposition. Fig. 3 is a view similar to Fig. 2,but showing the parts in their unlocked position.

Fig. 1 is a sectional view taken on the line 4--41 of Fig. 1 looking inthe direction of the arrows.

Fig. 5 isa sectional view on the line 5-5 of Fig. 1 looking` in thedirection of the ar.- rows. n n

Fig. 6 is a plan view of `part of the operating mechanism removed from`*the lock casing; and t Fig. 7 is a plan view of the opposite side ofthe mechanism shown in Fig. 6. n

In the drawings, I have shown a rim lock casing 10 having the mechanisminvolving my invention mounted therein; The casing 10 1s shown mountedupon the door 11, so

that a portion of this lock casing extends y beyondvthe edge of ythedooi` some distance, so that this projecting portion will cover a Jamstaplelor. strike 12 secured to the door provided with a base portion14;, which is L-shaped .1n cross-section, as shownin Fig. l, and thisbase portion is preferably mortised'in the door frame 13, as shown. TherlockgcasinglO` isfpreferably provided with an outwardly flaring portion15 surrounding framek 13. Thejam staple 12 ,is preferably the same, andin order that thiscasing may i be' iirmly secured to the door11,'anumber of screw-holes 16 are formed through this Haring portion of thecasing,rin which seupon its trunnions. In order that thisbolt mayoperatively engage the projecting staple 12, I have formed intermediateof the ends thereof acurved linger 21 adapted to be hooked under thestaple 12 when the roller bolt is rockedto its locked position. In orderthat the portions of the bolt 2O lying to 'each side of the nger 21 willclear the parallel legs of the staple 12, when the roller bolt is swungto its locked position, I have cnt awayv thislbolt,-fas indicated at 22.The

body portion of this bolt is hollowed out or is given a shell-likeconfiguration, as shown 1n 41g. 1, y1n order that the interior thereofwillclearthe outer face of thestaple as the bolt is rocked intolockingengagement with this staple. p

I have provided the following mechanism operated by a thumb-turned hubfor rocking the `roller bolt 20 4into and out of locking engagement withthe staple 12. In `the outer.l `face of the casing 10 is preferablyrotatably mounted athumb-turned vhub k23, the same being provided with ashank 24, which extends into the casing 10, and upon the inner end ofthis'shank is rigidlysecured the wing member 25. In order that thethumb-turned hub will normally remain in the position iesy shown inFigs. 1 and 2, so that the oppositely projecting wings upon the member25 will be out of engagement with the sliding bar which they operate, 1provide the U-shaped spring 26 having parallel legs, as shown in Fig. 2,which resiliently engage the flattened 'faces ot' the elliptical plate2'? secured to the shank 24. The Ushaped spring 26 preferably has a loopformed at one end thereoii, which loop is secured to the inner face ofthe casing l0 by means of a washer and cooperating screw 28, as clearlyshown in Figs. l and 2, and in order to retain the parallel legs of themember 26 out ot engagement with the winged member 25, a washer or disk29 is preferably mounted between the elements and 27. The thumb-turnedhub 23 is pro vided to operate the sliding bar 30, which extendslongitudinally within the casing 10 and is mounted to one side of thehub 23, as shown in Figs. 2 and 3. rllhis sliding bar is provided withthe usual talons 3l adapted to be operativtly engaged by either wing ofthe member 25 to thereby impart a sliding` movement to this bar. 1norder that the bar 30 may be guided as it is operated back and forth, 1have provided the lugs 32 formed upon the inner face of the casing, asshown in Fig. l, and these lugs are received between the spacedprojections 33 and 34 formed upon the under face of the bar 30 .adjacentthe forward and rear ends respective ly of the same. Upon the forwardface rolf the sliding bar 3G is mounted a swinging tumbler 35, the samebeing pivotally mounted upon the bar by means ot a stud or pin 36. Thistumbler extends longitudinally of the sliding bar and is provided with aprojection 37 positioned between the spaced talons 3l, and adjacent thefree end of this tumbler is formed a lug 38 adapted to cooperate withthe post 39 which extends upwardly through .the relatively long slot 4()Yformed in the bar 30. 1n order that the tumbler will normally beretained in locking engagement with the post 39, 1 provide the spring41, one end of `which reacts against the lng 42 formed upon the slidingbar. Adjacent the forward end ot the sliding bar 30 is formed a notch43, which is adapted to receive one end of the link 44. rllhe other endof this link extends into a similar notch 46 formed in one face of theroller bolt 20. One end of this link 44 is operatively connected to thesliding bar by a pin 47, while the opposite end of this link isoperatively connected to the roller bolt in a similar manner.

From the construction so far described, it will be seen that wheneverthe thumb-turned hub is turned in the proper direction, one of the wingsupon the element 25 will be introduced between the talons 3l to engagethe projection 37 to force the same in a rearward direction suiiicientlyto disengage the `upon which it is mounted, l' provide a cylinder or anyother preferred type of lock 4S "having the escutcheon plate 49. Thislock is preferably` secured in a hole formed through the door by meansof a plate 50 clamped against the inner face ofthe door by the screws 51threaded in the lugs 52 provided upon theopposite sides of the lock 48.This lock 4:8 is preferably provided witha key barrel (not shown) to theinner end ot which is secured the key rod upon which is operativelymounted a rollback 54, which rollback is adapted to cooperate with thetalons 3l and the projection 37 in the manner above pointed out tooperate the y sliding bar. The interior of the casing l0 is preferablyclosed by a cap plate 55, which is secured in place by screws 56threaded into the projecting posts 57.

From the above description, when read in connection with the drawings,it will be seen that 1 have provided a very strong and durable lock, thelocking mechanism of which may be operated either by means ot a keyinserted from the outside of the door or by a thumb-turned hub upon theinside ot the door, and it will also be seen that the link 44 provides avery satisfactory means tor imparting a rocking movement to the rollerbolt 2O by moving` the sliding bar 30 in one direction or the other.

ltv will be apparent that various changes may be made in the particularembodiment ot my invention herein disclosed without departing` from thescope of my invention as defined inthe annexed claims.

In witness whereof, I have hereunto set my hand on the 17th day ofSeptember,

JOHN H. SHAW.
